Can red scars be restored to their original color?

Red scars are quite common in our daily life. Such scars tend to protrude forward and are higher than the average skin level. This situation is generally attributed to scar hyperplasia, which is caused by many factors, such as frequent consumption of irritating foods, allergic reactions on the skin, etc. There are also many treatment methods, the most common ones are laser therapy, radiotherapy and so on.

Laser treatment:

Laser is suitable for superficial depressed and hypertrophic scars. When the laser acts on the skin, only the scar part of the skin surface is affected by the laser, and other tissues are not affected at all. These parts that are not affected by the laser will accumulate more collagen and elastin, which help the new generation and rearrangement of collagen in the dermis. In addition, laser irradiation will produce photothermal effect, photochemical effect, pressure effect, electromagnetic field effect and biostimulation effect on skin tissue, so that the damaged dead tissue in the skin scar can be quickly pyrolyzed, vaporized, or broken into tiny fragments, which will be engulfed by phagocytes in the body and excreted from the body, thereby achieving the purpose of smoothing the scar.

Radiation therapy:

Radiation therapy is suitable for superficial hypertrophic scars. When the scar area is treated with radiation therapy, superficial X-rays and beta rays can significantly reduce the number of fibroblasts in the scar tissue, impair their function, reduce the synthesis of collagen fibers and matrix, and increase the decomposition of collagen fibers, thereby flattening and softening the scar area.

Dermabrasion surgery:

Dermabrasion is mainly suitable for superficial depressed scars. The principle of dermabrasion surgery is to smooth the epidermis of the uneven scars, and then through the wound healing process, new epidermis will grow again, making the scars blurred and improving their appearance. However, grinding surgery can only be limited to a safe depth and is powerless for scars that are too deep. Therefore, it is only limited to improving relatively shallow scars and must be performed multiple times to be effective.

Surgery:

For more severe superficial or hypertrophic scars, plastic surgeons may choose to use incision and suturing or skin grafting to improve and correct the scars. The cutting method is suitable for small concave and convex scars, such as chickenpox scars, ice pick-shaped acne holes, and scars that are too thick or concave. The surgical method is to excise the scar, then peel off the skin and subcutaneous tissue, reduce the tension on the wound and then carefully suture it to make it a more beautiful, thin, straight scar. However, unless it is absolutely necessary, it is best not to choose surgery to avoid the formation of new scars.
